Mistress Zephy loves to control people because she loves to be in control of everything all the time. Today the mistress felt like she had to deal with her man as he had been having too much fun without her and she was afraid he was going to cheat on her. So she made it look naughty and adventurous but her real intention was to make him wear a chastity device and have the chastity key hidden so that he would only use his dick when she was present.
